common/src/extension/function library

A collection of combinators and pure functions.

Constants

isTrue → const bool Function(bool x)
Tests whether the given boolean argument x is true.

Functions

constant<T, U>(T x) → T Function(U)
The Constant function.
curry2<A, B, C>(C f(A, B)) → C Function(B) Function(A)
Binary function currying. Allows for partial application of binary functions.
identity<T>(T x) → T
The Identity function.
isFalse(bool x) → bool
Tests whether the given boolean argument x is false.
isNotNull<T>(T? x) → bool
Tests whether the given argument x is not null.
isNull<T>(T? x) → bool
Tests whether the given argument x is null.
not<T>(bool p(T)) → bool Function(T)
Inverses a predicate boolean evaluation.
repeat(int times, void body()) → void
Repeatedly calls the given function body, the given amount of times.
